McDonald and Repatriation Commission (Veterans' entitlements)

This matter concerned an appeal by a widow regarding her eligibility for a pension following the death of her husband, Mr. McDonald, from prostate cancer. The core dispute revolved around whether Mr. McDonald's death was related to his operational service, specifically his time on the HMAS Sydney between Australia and South Vietnam in 1966. The Repatriation Commission had denied the claim, and the appeal was heard by Deputy President McDermott.

The legal issues before the court were whether the material before it raised a reasonable hypothesis connecting Mr. McDonald's death from prostate cancer to his operational service, and whether this hypothesis was supported by the relevant Statement of Principles (SoP). This required the court to apply the four-step test established in *Repatriation Commission v Deledio*. The court specifically considered whether the veteran met the minimum exposure requirements stipulated in the SoP concerning malignant neoplasm of the prostate.

The court acknowledged that the material did point to a hypothesis connecting Mr. McDonald's condition to his service, particularly his time on the HMAS Sydney, which included a familiarisation period. However, when assessing the third *Deledio* step, the court found that the material did not satisfy the minimum 30-day exposure requirement under clause 6(b) of the relevant SoP, which pertains to exposure to potable water. Furthermore, the material did not satisfy the factors in clause 6 of the SoP relating to defence service.

Consequently, the court concluded that a reasonable hypothesis connecting Mr. McDonald's death to his operational service, as supported by the relevant SoP, was not raised. The decision under review, which affirmed the Repatriation Commission's denial of the pension, was therefore affirmed.
